The invention relates to a deicing power transmission line of multiple conducting wires. Multiple (more than two but less than four) power transmission lines arranged in parallel in the same direction form a line set, wherein the lines are mutually separated and arranged in zones. Conducting wires at two ends of each line set of each zone are connected with a breaker respectively, and the breakers at two ends of each zone are communicated. Under normal condition, all breakers at two ends of each line set of each zone are switched on and powered, and the conducting wires do not heat. Once the conducting wires are iced heavily, when a section of the conducting wire needs to deice, one line in the breaker at any end of the line set is reserved, and the rest lines are switched off and not powered. Thus, only one conducting wire is switched on and powered to bear overall electric quantity of the line set, the current is increased and the line heats, and then the line melts ice so as to deice. In the same way, when the breaker is transformed, any conducting wire can melt the ice. When the ice is melted, the normal condition recovers.
